A method for heating a preform (1), the method comprising: introducing the preform (1) into a heating device (5) comprising an array of infrared emitters (50) arranged in a plurality of columns (Cj) and a plurality of rows (Ri); angularly orienting the preform at an input angular position by rotating the preform about the longitudinal axis; setting the power levels of the infrared emitters (50) so as to divide the array of infrared emitters (50) into column subsets (SCn), each column subset (SCn) generating heat at a different power level than an adjacent column subset (SCn); and heating the preform (1) with an array of infrared emitters (50) while translating the preform (1) at a translation speed in a direction parallel to rows (Ri) of the array and while rotating the preform (1) at a rotational speed about a longitudinal axis (A1) of the preform in front of the infrared emitters (50). 一种用于加热预成型件(1)的方法，该方法包括：将预成型件(1)引入到加热装置(5)中，该加热装置包括以多列(Cj)和多行(Ri)排列的红外发射器(50)的阵列；通过围绕纵向轴线旋转预成型件，在输入角度位置处将预成型件成角度地定向；设定红外发射器(
